Safety start interlock system
The tractor is equipped with a safety start interlock system consisting of
the park brake switches, seat switch, and deck clutch switch.
Check tractor safety start interlock system daily, prior to operation.
This system is an important tractor safety feature. It should be repaired
immediately if it malfunctions. The machine incorporates a separate seat
switch which will stop the tractor engine when the operator is unseated for
any reason while the tractor is operating. This is a safety feature designed to
prevent runaway or accidental entanglement. To inspect the system:
1. The operator must be on the seat when testing the seat switch.
2. Set both steering control levers in the park brake position.
3. Start the engine and allow it to warm up to operating temperature.
4. With the deck clutch switch down and the steering control levers in the
park brake position, slowly raise off of the seat. The engine should con-
tinue to run.
5. With the deck clutch switch up and/or the steering control levers in the
neutral, forward or reverse position, slowly raise off of the seat. The
engine should stop.
6. If the engine fails to stop when the deck clutch switch is up or one or
both of the steering control levers are up and the operator is off the seat,
check the function of the seat switch. If the seat switch is not operating
properly (is not opening or closing) and if the cause can not be deter-
mined, replace the seat switch.
If the problem can not be located, contact your Hustler Dealer.
WARNING: The safety interlock system should always func-
tion per steps 4 and 5. If it does not function properly, it
should be corrected immediately. Do not operate machine
without properly functioning seat safety switch.
Engine starting
The tractor’s safety start interlock system is also designed to protect the
operator and others from accidental injury due to unintentional engine start-
ing. The engine starting motor will not engage until:
A. Steering control levers are in the park brake position.
B. Deck clutch switch is in the down (OFF) position.
WARNING: The safety interlock system must not be discon-
nected or bypassed. Doing so could cause the machine to
operate unexpectedly resulting in personal injury.
NOTE: The operator’s seat is equipped with a separate safety switch. If
for any reason the operator should become unseated when the steering con-
